Fire-Rated Drywall: Essential for Fire Safety in Construction

Fire safety is a crucial consideration in building construction, and fire-rated drywall plays a key role in enhancing the fire resistance of walls and ceilings. Unlike standard drywall, fire-rated drywall contains special additives like glass fibers and non-combustible materials, which slow down the spread of flames and provide valuable time for evacuation in case of a fire.

Types of Fire-Rated Drywall

1. Type X Drywall – Typically 5/8-inch thick, it provides at least 1 hour of fire resistance when properly installed. Commonly used in multi-family homes, commercial buildings, and garages.

2. Type C Drywall – A more advanced version of Type X, designed with enhanced fire-resistant properties for 2-hour fire-rated assemblies.

Where to Use Fire-Rated Drywall?

• Between attached garages and living spaces

• In multi-unit buildings (apartments, condos, offices)

• Around furnace rooms and electrical panels

• On ceilings for improved fire protection

Building Code Compliance

Ontario’s Building Code (OBC) and the National Building Code of Canada (NBCC) mandate the use of fire-rated drywall in specific areas to meet fire safety regulations. Proper installation, including correct fastening and taping, is essential to ensure compliance and effectiveness.
